Serial No. 641,822.

T0 all whom 'it may concern Be it known that I, WILLIAM T. JoYNnn, acitizen of the United States, residing at Suffolk, in the county ofNansemond and State of Virginia, have invented certain new and usefulImprovements in Peanut Separatore, of which the following is aspecification.

This invention comprehends certain new and useful improvements inharvesting machinery for peanuts and similar crops, and the inventionhas for its primary object a simple, durable and e'ficient constructionof peanut picker embodying a novel and useful shaking shoe or screeninto which the peanuts are fed from an inclined elevator or conveyerwhich in turn receives the peanuts, vines and trash from a beater ordrum, the parts being so arranged that they may be easily manufacturedand assembled and may be driven with comparatively little power, thestrain of the driving belts or similar elements being effectivelydistributed so as to avoid any undue strain on any one part. And theinvention also aims to generally improve this class of apparatus and torenn der it more useful and commercially desirable.

With these and other objects in view, as will more fully appear as thedescription proceeds, the invention consists of certain constructions,arrangements and combinations of the parts that I shall hereinafterfully describe and claim.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawing in which: Figure 1 is alongitudinal sectional view of my improved peanut picker; Fig. 2 is atop plan view, parts being omitted to show the interior construction;Fig. 3 is `a detail perspective view of a shaking shoe employed.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The framework A of my improved peanut picker may be of any desired size,construction, and design, and may be so arranged that it may be'supported inv a stationary manner or mounted upon trucks, either detaehably or permanently, so that it may be easily carried from place toplace. In the present embodiment of the invention illus trated in theaccompanying drawings, said framework embodies uppeisills 1, lower sills2 parallel to the sills 1, and any desired number of connecting uprights3, together with any desired number of cross bars or braces.

At the rear of the machine, denoted as such because the peanuts arefinally discharged from such end, the upper sills 1 support upright andlaterally spaced side boards l between which an inclined board is set soas to constitute, with the side boards 4l, an inclined chute, into whichthe peanuts on the vines are fed, preferably by hand. In the preferredconstruction of the apparatus, the inclined board 5 is secured in placedetachably by tie rods 7 connected to the side boards et, whereby theboard 5 may be detached whenever desired so as to obtain a view of andaccess to the subjacent parts, for the purposes of repair or the like.

The chute discharges into the month 8 of a casing 9 which is supportedin the framework A, said casing including a lower relatively stationarysection 10 inclosed in the framework, and a hinged top section 11preferably provided with a latch or latches 12 by which it may besecured in closed position. The mouth 8 of the casing is prefer ablyformed by extensions 8a on the top section 11, as clearly illustrated inthe drawing. A beater' cylinder 13 is journaled in the casing 9 on atransversely extending shaft 13a mounted in suitable bearings on theupper sills 1, and said cylinder is preferably provided with any desirednumber of inset bars 111 of metal or other substance provided with anydesired number and disposition of teeth 15 which in the present instanceproject radially (although not neces sarily so) and are arranged incircumferentially spaced transversely extending sets. These teeth 15co-act with pickers 16 arranged in any desired way in the casing 9 andprojecting in any desired direction from the inner wall thereof, thepickers 16 in the present instance being also secured to or formed onmetallic or other inset bars 17, as shown.

As the peanuts, clinging to the vines, are tossed or dumped on to thechute, they are fed thereby into t-hc mouth S of the casing 9 and, thevines meeting the revolving teeth 15 and the relatively stationarypickers 16, are

broken up and the peanuts separated therefrom, the whole being finallydropped from the casing on to the upper stretch of a rearwardly andupwardly inclined conveyer 13 mounted in the framework below the bottomboard of the chute.

The conveyer B, in the present embodiment of the invention, includes aninclined bottom board 18, a series of transverse slats 19 adapted toslide upon the upper surface of said board, and sprocket chains 20 towhich the slats are connected in any desired way, the sprocket chainspassing over sprocket wheels 21 that are secured to upper and low-ertransverse shafts 22.

'which project inwardly, that is, rearwardly, from that wall or side. ofthe shoe which lies approximately directly under the discharge end ofthe conveyer, and the broken vines and lighter trash are blown out fromthe rear end of the machine by means of a blast of air issuing from theflue 24, while the peanuts are dropped through or off of the fingers 23into the bottom of the box or shoe C, most of them falling upon a r)Sheflue 24 extends upwardly and rearwardly from a fan casing 26 in which afan 27 is mounted, the fan being'secured upon a transverse shaft 28, asshown.

It will be noted that the free ends or exf tremities of the fingers areturnedv upwardly so that the material depositedv thereon can not slidedirectly oftl the fingers but willl be held thereon so that the heavierand lighter particles will bev separated by the vibrations It will alsobe noted that the screen extends across the upper end of the blast flue24 so that the air blast will be directed through the screen onto thematerial falling from between the fingers and the peanuts will be fedinto the chute by the vibrations of the shoe while the pieces of vinesand other light particles will be blown out beyondv the ends of theseparating fingers. The rear side of the box is l formed by an end gate29 which is pivotally mounted in the sides of the shoe and extendsbetween the same andv is so disposed that it depends into the chute 30,as clearly shown inv Fig. 1. The end gate may be readily adjusted so asto more or less close the entrance to the discharge chute 30 and at thesame time enla rge the escape opening between the gate and the ends ofthe separating lingers so that if the vines should be G5" excessive theblast may act efectually thereon so as to blow from the shoe all piecesof the vines and leaves, and very little, if any, ofl these elementswill pass into the chute.

The bottom of the shoe C is open, as shown, save for the screen 25, saidopen bottom overlapping the forward side of the laterally inclined chute30, the wires forming the screen being secured to said side, as clearlyillustrated in the drawing, and as the peanuts drop into the shoe and onto the screen, they pass or are blown into the chute 30 and aredeflected from said chute into a cleaning and stemming drum D.

The drum D is in the present embodiment of the apparatus constructed ofa predetermined number of spoked pulleys or heads 31 mounted upon atransverse shaft 32 journaled in bearings in the framework, said headsbeing spaced from each other a distance sufficient to permit of thepassage into the frame of saws or toothed disks 33, of which there maybe any desired number in a set and any desired number of sets. In thepresent instance there are two sets of these toothed disks, the samebeing mounted upon transverse shafts 34C journaled in the framework. Thepurpose o'f these saws or toothed disks is to cut off and otherwiseremove from the nuts the small stems which might up to this time adherethereto in the harvesting operation, and as the spoked heads 31 arepreferably octagonal or otherwise polygonal in shape, it will be clearthat the peanuts will be tumbled around in the drum and thus be cleaned,being nally discharged from one end of the drum into any suitablereceptacle (not shown).

It is to be understood that any desired mechanism may be employed fordriving the various parts and for shakius` the shoe C and that variouschanges may be made in the construction, arrangement and propor* tionsof the parts without departing from the scope of the invention asdefined in the appended claim. For the driving mechanism however, Iprefer to use the following elements, although it is to be understoodthat while belts or pulleys and band wheels are mentioned, they are tobe considered the eouivalent of sprocket chains and sprocket wheels. Themain or beater shaft 13a is driven from any suitable source of power(not shown), by mea-ns of a main driving pulley 35 at one side of themachine, and on the opposite side of the machine said shaft 18a carriesa relatively small pulley over which a belt E passes. The belt E alsopasses over a pulley 37 on a shaft 38 extending transversely of themachine above the' side boards 4, thence around a pulley securedv to oneend of the drum shaft 32` thence around pulleys on the saw shafts 34 andthence around a pulley on the upper conveyer shaft 22. A relativelylarge pulley is also secured to the shaft 13l at this side of themachine, and a belt F passes around said pulley and also around a pulley43 on one end of the fan shaft 28, whereby the conveyer, the cleaningand stemming drum, the stemming saws, and the fan are all actuated fromthe main shaft 18a of the machine, practically the entire strain of theoperating parts or the power imposed thereon being taken up largely bythe beater shaft and being properly distributed therefrom.

In order to operate the shoe C, the shaft 38 carries, on that side ofthe machine where the drive pulle is mounted, a pulley 44, and a beltpasses around the pulley 44 and also around a pulley 45 on a crank shaft46 journaled in the framework. The cranks of the shaft 46 are connectedby links 47 to t-he shaking shoe C, whereby, as said shaft is rotated, avibratory movement will be imparted to the shoe.

From the foregoing description in connect-ion with the accompanyingdrawings, the operation of my improved peanut harvesting machine will beapparent, as the operations of the different parts have been set forthin detail hereinbefore in connection with the description of theconstruction and relative arrangement of parts.

What I claim is:

A separator provided with a shaking shoe embodying a box formed with oneside and two ends and open at its top and bottom and the other side, achute secured to the box at the bottom thereof and at the open side, ascreen secured to the other side of the box and to the adjoining side ofthe chute, a series of separating fingers secured at one end to the lastnamed side of the box at the top thereof and terminating in spacedrelation to the open side of the box, and an end gate tiltably mountedin the open side of the box and extending down into the chute.

In testimony whereof, I affix my signature in presence of two witnesses.
